IMPROVEMENT IN THE MACHINE FOR BREAKING AND SOFTENING HIDES, SKINS, a'ND LEATHER.
Specification forming part of Letters Patent No. 229, dated June 10, 1837.
To all luhom it may concern.:
Be it known that I, Eli Kendall, of New-
ton, in the county of Middlesex and State of
Massachusetts, have invented a new and use-
ful Improvement in the Machine for Break-
ing or Softening Hides, Skins, and Leather;
and I do hereby declare that the following is
a full and exact description of the said ma-
chine as invented or improved by me.
First. I construct a frame about five feet in
length, four feet six inches in breadth, and
three feet high.
Second. I have a cast-iron cylinder or beam
about fourteen inches in diameter and four
feet six inches in length, turned straight and
Third. I have a self-feeding roller on the
top of the cylinder or beam, which prevents
the hides, skins, or leather from passing
through any faster than the cylinder or beam
Fourth. I have an iron or wooden cylinder
about four inches in diameter, on which are
fastened by screws what I term my " spring "
or "elastic" breakers, more particularly de-
scribed below. This cylinder, with the break-
ers, is placed on the top of the other cylinder
or beam near the self -feeding roller, and per-
forms the breaking or softening by revolving
against the hides, skins, or leather as they
pass through over the cast-iron cj^inder.
A more definite description of this machine
will be had by reference to the drawings ac-
companying this specification.
A represents the cast-iron cylinder which
the hides, skins, or leather are carried over,
passing at the same time under the self-feed-
ing roller B and the breaker-cylinder C.
B represents the self-feeding roller.
C reijresents the breaker-cylinder, on which
are fastened the spring or elastic breakers,
which perform the work of breaking or soft-
ening hides and skins for the lime, and also
of softening and skiving leather. For more
convenient description I have marked but
one of the breakers, which is marked 5 && 6 a
in Figure 1 on the drawings. They each con-
sist of a steel plate about five inches in length
and one-eighth of an inch in thickness. One
end is cut with a miter, and about one inch
of the length at this end is bent so as to be
at right angles with the rest of the plate, be-
ing the part marked a. The part bhbb is
the spring of the breaker, and is bent so as
nearly to fit the surface of the cylinder. The
part a is that which performs the breaking,
and has a rounded edge, so as not to cut the
hides, &c. One end of the part b & 6 5 is
fastened to the cylinder by the tight screw c,
and the remainder, with the breaking part a,
moves in a direction perpendicular to the sur-
face of the cylinder, the distance from the
cylinder within which they shall move being-
regulated by means of the set-screw d. These
breakers are placed in a direct line around
the cylinder, being placed in pairs from the
center, their edges lapping about one-half of
an inch, so as-to break the joints. As the cyl-
inder revolves they perform a drawing stroke
on the hide, skin, or leather, so as not to tear
or otherwise injure the same.
D represents the screws for raising andlow-
ering the breaker-cylinder C a proper space
from cylinder A, as the thickness of the
hides, -skins, or leather may require. _ .
E represents screws forincreasingordimin-
ishing the power of springs F.
G represents levers resting across the bear-
ings of the feeding-roller B.
H represents weights connected with the
ends of the levers G for the purpose of bear-
ing or pressing the feeding-roller B upon the
F represents springs for pressing the break-
er-cylinder against the hides,' &c., more or
less, as they may require.
L represents pulleys or gearing for putting
the several parts of the machine in motion.
What I claim as my invention, and desire
to secure by Letters Patent, is—
The spring or elastic breakers constructed
and applied to the machine for breaking or
softening hides, skins, and leather, as above
I do not claim the spiral form of the break-
ers as my invention.
